SPECIFICATION forming part of Letters Patent No. 765,913, dated July 26,1904.

Application filed August 31, 1903.

To all whom it nuu concern.-

Be it known that I, J OHN BOYD, a subject of the King of Great Britainand Ireland, residing at Bothwell, county of Lanark, Scotland, haveinvented Improvements in Mechanism for Driving Flier or Like Spindles ofSpinning, Twisting, or Like Machines, of which the following is aspecification.

This invention comprisesimprovements designed for spinning, twisting,winding, and similar machines fol-fibrous material, and pertainsparticularly to an improved combination of mechanism for drivingspindles of said machinery by which all the spindles on both sides of aframe, or in sections thereof, are driven by one long endless band; andthe invention consists,mainly,in using two long centraldriving-cylinders working side by side, which may be made the wholelength of the frame to actuate one or a number of such bands, each bandbeing employed to drive a number of spindles on both sides of the frame,each band being provided with two or more stationary guide-pulleys tobring back latter to the place from which it starts and when necessary(as it is in most cases) to use also in combination with same a movabletensionpulley or some other mechanism for the purpose of tensioning eachband, whereby a more uniform speed and driving power is imparted to allthe spindles (or in case of dead-spindles to the tubes or fliers whichwork thereon) the wear and tear of bands is reduced, extra expenditureof power due to overtight bands is prevented, and a uniform twist isimparted to any fibrous material which may be spun thereby.

In order more fully to describe my improvements and to show how they maybe carried into effect, I will'describe their application, as shown intwo accompanying sheets of drawings.

On Sheet 1, Figure 1 is a vertical section of so much of aspinning-frame as is neces sary to illustrate certain parts of onemodification of my invention, and Fig. 2 is a plan view of same. OnSheet 2, Fig. 3 is a vertical section, and Fig. 4: a plan View ofanother modification.

In the drawings the same reference-numer- Serial No. 171,440. (Nomodel.)

als are used to mark the same or like parts wherever they are repeated.

In the construction illustrated in Figs. 1 and 2, Sheet 1, I have shownmy improved mechanism as applied to a section of an ordinaryring-spinning frame 19, having ten spindles 20 on each side, all drivenby one long endless band 21,actuated by two central hori- Zontaldriving-cylinders 22 and 23, placed side by side and by preference inrelation to one another and to the pindles on each side (as it sohappens) exactly as they are usually placed in frames of this class wheneach spindle is driven by its own band, and so making my presentimproved method of driving a number of spindles by one long endless bandvery easy 'to apply to such frames. The cylinders 22 and 23 aresufficiently under the center of the pulleys 20 of the spindles 20 oneach side to prevent the runningband 21 as it goes between latter fromcoming in contact with the tops of the cylinders 22 and 23 and also tokeep all the parts of the band clear of one another where they crosseach 'others path. In banding the spindles 20from the beginning to theend of any section of the frame which the band drives it is first bypreference passed once round the two cylinders 22 and 23 and thenalternately round two opposite spindles 20 and round the outsides of thetwo cylinders 22 and 23 till the last two spindles of the section arebanded, after which it is taken once more round the two cylinders andround two stationary guide-pulleys 24 and 25, placed at opposite ends ofthe section, and back to the starting-point, when its two ends arefastened together after being drawn sufficiently tight. Both cylindersare driven in one direction, and the band 21 by the use of the twocylinders 22 and 23, placed side by side, instead of one cylinder, asshown in Fig. 1, Sheet 1, in British Patent No. 18,860 of 1901, has abetter run between the spindles 20, and the cylinders 22 and 23 give amore powerful and regular drive to the spindles and without undulylowering the cylinders 22 and 23 and without the aid of an auxiliaryangled cylinder 23, as shown in Fig. 3 of specification above referredto, or the use of coned pulleys, claimed in British Patent N 0. 17,795

of 1900, to guide and keep the coils of the band 21 clear of one anotherand also keep it from lapping. The stationary guide-pulleys 24 and 25used are by preference similar to what are described in the BritishPatent No. 18,860 of 1901, referred to, running in adjustableoil-cup-socket brackets 26 and 27 and carried on a longitudinal'bar 28,placed,preferably, in a central position above the two driving-cylinders22 and 23, it being possible in favorable circumstances and with a bandof suflicient elasticity to drive a number of spindles to advantage, asdescribed, without the aid of a tension apparatus.

In the modification illustrated in Figs. 3'and 4, Sheet 2, I have shownmy improved mechanism as applied to a section of a similar frameprovided with a tension-pulley apparatus to regulate the tension of theband 21. The spindles 20, the band 21, the two central cylinders 22 and23, the stationary guide-pulleys 2 1 and 25, their oil-cup-socketbrackets 26 and 27, and the longitudinal bar 28, carrying same, areshown in the same position; but in this case one of the stationary guidepulleys, 24, used is a double-grooved pulley, same as shown in Figs. 6,9, 10, and 13 of the British Patent No. 18,860 of 1901, referred to, anda tension-pulley 29 is provided, running in an oil-cup socket of atension-carriage 30, the latter being pulled along the bar28 byaclockspring apparatus or by the action of adjustable weights 31 and 32on a cord 83, connected to the carriage for the purpose of tensioningthe band 21, all as described in British specification referred to.

Instead of the guide and tension pulley brackets of my improvedmechanism being carried on a longitudinal bar the lattermight in somecases be dispensed with, and the guidepulley brackets might be fixed tosome convenient part of the frame and the tensioncarriage when latter isused made to move on a longitudinal rail of the frame or on alongitudinal bracket fixed to same.

Flat as well as round bands, if not too broad, can be used with myimproved mechanism, as shown in Figs. 1 to 4, if the spindle-pulleys 20and the guide and tension pulleys are made suitable for same and if incase of broad bands an extra guide-pulley is supplied to lead the flatband back to or from the top of the cylinder.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In mechanism for driving spindles of spinning,twisting, winding and like machines the combination with two longcentral and parallel driving-cylinders located between the spindles onboth sides of the machine-frame of a long endless band arranged to driveall the spindles of the frame or of a section thereof and two or morestationary guide-pulleys to bring back the band to the starting-pointsul stantially as described.

2. In mechanism for driving spindles of spinning, twisting, winding andlike machines the combination with two long central and paralleldriving-cylinders located between the spindles on both sides of themachine-frame of a long endless band arranged to drive all the spindlesof the frame or of a section thereof, two or more stationaryguide-pulleys to bring back the band to the starting-point and a movabletension-pulley for automatically tensioning the band substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN BOYD.
